Mel Gibson was on Joe Rogans show saying the same thing. Said he had multiple friends with cancer. They did parasite cleanse and this methane blue treatment and are cancer free. A research team from the University of São Paulo published a paper titled “Methylene blue photodynamic therapy induces selective and massive cell death in human breast cancer cells” in BMC Cancer in 2017, showing that methylene blue becomes highly cytotoxic to breast-cancer cells when activated by 640-nm light. In their in-vitro experiments, breast-cancer cell lines were treated with methylene blue and then irradiated at 640 nm (4.5 J/cm²), which caused extensive destruction of cancer cells while normal breast epithelial cells were far less affected under the same conditions.
